5GHz hairpin bandpass on high end fiberglass (Megtron-6)

  • Thread starter the_emi_guy
  • Start date
In summary, the conversation discusses the use of a distributed element hairpin filter on high-end fiberglass PCBs, specifically Panasonic Megtron-6 versus Teflon. The speaker suggests looking at the Loss Factor for each option and mentions the possibility of hermetically sealing the RF board. However, they typically use discrete filters instead. The conversation also touches on the availability of simulation tools and mentions concerns about moisture absorption and glass weave issues.

Anyone have experience putting distributed element hairpin filter (<5GHz) on high-end fiberglass, such as Panasonic Megtron-6 PCB (vs. Teflon)?

Not directly, but look at the Loss Factor for each. It may affect the available Q.

No hermetic seal, moisture absorption was one of my concerns. Also concerned about glass weave issues.
Probably not going to attempt it, just curious if anyone out there has been down that road.

1. What is a 5GHz hairpin bandpass filter?

A 5GHz hairpin bandpass filter is a type of electronic filter that is designed to pass a specific frequency range, while rejecting all other frequencies. It is commonly used in communication systems to isolate and amplify signals in the 5GHz frequency range.

2. Why is it important to use high end fiberglass (Megtron-6) for this type of filter?

High end fiberglass, specifically Megtron-6, is known for its excellent electrical properties, including low dielectric loss and low signal attenuation. This makes it an ideal material for constructing sensitive electronic components, such as a 5GHz hairpin bandpass filter, which require high-frequency precision and minimal signal loss.

3. How does a hairpin structure help in the design of a bandpass filter?

The hairpin structure, which consists of multiple parallel resonant circuits, helps to increase the filter's selectivity and bandwidth. This allows for a more precise and efficient filtering of the desired frequency range, while suppressing unwanted frequencies.

4. Can a 5GHz hairpin bandpass filter be used in other frequency ranges?

Yes, the design of a hairpin bandpass filter can be adjusted to work in different frequency ranges. However, the specific dimensions and parameters of the filter will need to be recalculated and optimized for the desired frequency range.

5. What are the advantages of using a hairpin bandpass filter compared to other types of filters?

A hairpin bandpass filter offers several advantages, including high selectivity, low insertion loss, and a compact size. It is also relatively easy to construct and can be customized for specific frequency ranges. Additionally, the hairpin structure can be easily modified to create different types of filters, such as bandstop or notch filters.
